NE Tasmania Exploration

Stellar’s wholly owned subsidiary, Tarcoola Iron Pty Ltd, holds five Exploration Licences in NE Tasmania (EL15/2020, EL16/2020, EL19/2020, EL11/2020 and EL12/2020) covering a combined area of 648km2 which is prospective for gold, tin, lithium and base metals.

North Scamander Project

Stellar’s maiden exploration drillhole NSD005 completed in August 2023 confirmed a significant new high-grade Ag-Sn-Zn-Pb-In polymetallic discovery at the North Scamander Project.

Significant intercepts within the Upper Vein-Breccia Zone intersected in NSD005 included:

  • 32.0m @ 141 g/t Ag, 0.34% Sn, 3.8% Zn, 2.0% Pb, 77 g/t In and 19 g/t Ga from 130.0m
  • Including 5.0m @ 495 g/t Ag, 1.04% Sn, 5.2% Zn, 7.1% Pb, 113 g/t In and 23 g/t Ga from 130.0m
  • Including 1.4m @ 353 g/t Ag, 2.29% Sn, 14.2% Zn, 8.8% Pb, 594 g/t In and 29 g/t Ga from 159.7m

Individual assay results within this outstanding intercept included; 1,035 g/t Ag, 5.75% Sn, 27.6% Zn, 21.2% Pb, 1,070 g/t In and 37 g/t Ga.

The Upper Vein-Breccia Zone contains sphalerite, galena, minor chalcopyrite, and associated pyrite hosted in massive veins, semi-massive veins, hydrothermal breccia and associated stringer-style veins.

The high-grade multi-commodity North Scamander discovery has similarities with the Sn-Ag polymetallic systems of world-class Bolivian Tin Belt.

Significant grades of critical minerals Indium and Gallium also recorded. The 77g/t average Indium grade over the 32m significant intercept compares favourably with Indium grades in known Indium-Base Metals deposits globally.

Lower Stockwork Zone

Results for the Lower Stockwork Zone intersected in NSD005 returned anomalous copper levels including 96.0m @ 0.04% Cu from 369.0m consistent with the pyrrhotite +/- chalcopyrite stockwork veining logged over this interval.

These results confirm a change in mineralisation style and metal tenor from the sulphide vein and breccia hosted Ag-Sn-Zn-Pb-In mineralisation in the Upper Vein-Breccia Zone to pyrrhotite-dominant stockwork-hosted low-grade Cu mineralisation in the Lower Stockwork Zone. The  results are interpreted as a possible ‘near-miss’ indicator of a potential tin system, or the low-grade margins to a copper-dominant system, with the core of the regional scale magnetic anomaly yet to be tested.

Follow up Drill Targets

The North Scamander Project is prospective for 3 styles of mineralisation;

  1. High grade polymetallic vein and breccia-hosted Ag-Sn-Zn-Pb-In systems (NSD005 Upper Zone), that tend to be offset from the magnetic anomaly. This will be the immediate focus for follow up drilling at North Scamander.
  2. Stockwork-hosted Cu (and possibly Sn) mineralisation, coincident with pyrrhotite and therefore the main magnetic anomaly at North Scamander, which is yet to be fully tested.
  3. Greisen-style potential Sn-Li mineralisation associated with the preserved granite cupola at depth.
